MACHINE FOR SEAMING HEADS ON CANS.

TAIL-52,188.

To all whom it may concern: Be it known that 1, PETER KRUSE, a c tlzenof the United States, residing in the borough of Brooklyn, county ofKings, city and State of New York, have invented certain new and usefulImprovements in Machines for Seaming Heads on Cans, of which thefollowing is a specification.

This invention relates to machines for seaming heads or ends on cans or,canbodies, and aims to provide improvements therein.

The machine of the present lnventlon 1s of the type known as two-spindlemachines, and contains improvements whereby the seaming operation may beunder the ready and constant observation of the operator, and wherebyany irregularlties 1n the operation of the seaming mechanlsm may bereadily observed and quickly and readily rectified.

The invention further provides improvements in the general machinestructure.

The invention further provides improvements in the seaming mechanismwhereby changes may be made for adapting the mechanism for operating ondifferent sized cans with greater readiness than heretofore.

An embodiment of the invention is illustrated in the accompanyingdrawings, wherein Figure 1 is a front elevation; Fig. 1 is a fragmentaryside elevation of the top part of the machine; Fig. 2 is a horizontalsection on line 2-2 of Fig. 1; Fig. 3 is a horizontal section on line3-3 of Fig. 1; Fig. 4 is a top-plan View with parts broken away to showone of the seaming mechanisms; Fig. 5 is a diagrammatic viewillustrating the action of the seaming rolls upon a canhead; Fig. 6 is aview in elevation (with parts in section and parts omitted) of theseaming mechanism; Figs. 7, 8 and 9 are views of a similar seamingmechanism to that disclosed in Figs. 4, 5 7 being a horizontal sectionalview through the upper part of the seaming mechanism, Fig. 8 adiagrammatic view similar to Fig. 5, and Fig. 9 a vertical section ofthe mechanism with parts in elevation.

7 mechanism, and B a second seaming mech anism.

a and b are, respectively, the seaming heads of the mechanisms A and B,carrying, respectively the seaming rolls a and I).

he seaming heads a and b, respectively, are driven" by the spindles Cand D, which i are rotated from a vertical drive-shaft E through theintermediary of a gear 6 and pinions c and d respectively. Thedriveshaft E may be driven in suitable manner by means of a pulley Fmounted upon a horizontal shaft f and connected to the shaft E throughsuitable bevel gears 7.

l G designates a turntable which may be provided for receiving the cans.The turntable G is preferably driven from shaft E by sets of gears g gon the shafts H and I are feed tables for the cans or bodies, and J andK are feed disks. The feed disks J and K are intermittently actuatedpreferably through a Geneva wheel L driven shaft E, andgear wheels Z Zconnected to the shafts j and is of the disks J and K. The feed disk Jreceives the cans from the turntable G and carries them past a suitableselective can-head feeding mechanism M to a position beneath the firstseaming mechanism A, and the feed disk K carries the cans with the headspartially seamed there on to a position beneath the second seamingmechanism B, where the seaming is completed, and from thence on to asuitable carrying-ofl device N. The feed disks J and K rotate inopposite directions, and the disk K rotates toward the front of themachine, in such manner that the cans with the partially seamedcan-heads thereon, coming from the seaming mechanism A, are moved to thefront of the machine, clear of the seaming mechanism and in clear viewof the operator, where they may be readily observed or examined by theoperator. The feed tables H and I are provided with guides in and z forthe cans, and the guide 2' is preferably provided with removable orpivotal portions i i which may be readily swung open so as to providefor ready removal of the can for inspection or rejection. The feed disksJ and K are adapted'to the main match beneath the first seamingmechanism in such manner that when the can is in position in thefirstseamlng mechanlsm t is rounded or straightenedup into its properthey are raised against the chucks a and b respectively of the seamingmechanisms by the plungers O and P respectively. The plungers O and Pare actuated by a slide Q, sliding in usual ways on the main frame,which slide is raised and lowered by a cam q mounted upon thedrive-shaft E which acts upon a roller g upon the slide Q. The slidepreferably acts upon the plungers O and P through resilient means suchas springs 0 and p.

The seaming mechanisms A and B (Figs. 49) comprise the seaming heads aand b, which are fixed upon the hollow rotary spindles C and D. Theseaming rolls a a and b b are carried by arms a a? and b b respectively,fixed upon pins a a 12 5*, which are pivotally mounted in the seamingheads a and b respectively. The sealing rolls a. a, and b b are movedinwardly into contact with the can-heads or ends by means of hoods orshells R and S carrying cams adapted to engage shoes a a and b b mountedon arms a a and b b fixed upon the pins a a and b b respectively. Thehoods or shells R and S are mounted upon rotary hollow shafts r and srespectively which are journaled in a. slide T which is suitably guidedupon the main frame of the machine, and is moved up and down by a cam tmounted upon the drive-shaft E, the cam acting upon a roller 25 carriedupon the slide T. The shafts 1' and s, are keyed to the spindles C and Dand partake of the rotary movement thereof. Up and down movements of thehoods Rand S under the influence of'the cam 25 brings the cams carriedby the hoods into and out of contact with the shoes a 12 andconsequently effects the inward movement of the rollers against thecan-heads, and the release of the rollers, the rollers moving outwardlyby centrifugal force.

'The hoods or shells R and S 'are preferably formed as separate parts,and connected to flanges 1' s which may be provided upon the shafts rand 8. The hoods R and S are preferably provided with a plurality ofsets of cams 1* r 1' 1' 7' r 8 s, s s, s 8 The cams of the respectivesets upon each hood are at different radial distances and are henceadapted to move the rollers inwardly to progressively greater extent, insuch manner that the seaming roll. may be made to operate upon cans ofdifferent diameters by selecting :an appropriate set of cams. Theseveral sets of cams on each of the hoods R and S may be brought intoproper position for engaging the shoes connected with the severalseaming rolls, by removing the bolts 7' s and shifting the hoodscircumferentially to a proper position. For positioning the hoods uponthe shafts, the flanges r? ands may be provided with a plurality ofholes 1' 1' r, and the hood with a hole 1" through which a pin 7* isadapted to be inserted into one of the holes 1", 'r' or 1', as shown inFig. 4. For convenience and expedition in placing the hoods on andtaking them off the shafts r and s, the hoods are each constructed intwo or more parts adapted to be separated and be brought together aroundthe shafts. The different parts may be connected by cleats r, as shownin Fig. 4.

The chucks a and b are carried by hollow sleeves a (4 extending throughthe hollow spindles C D and fixed in brackets a, b at the top of themachine. Knock-outs U and V extending through the hollow slee 'es a bmay be provided. The knock-outs may be operated by a cam u whichactuates a roller '0 on the end of a rod 12 connected to a rock-arm 0connected to the knock-outs U and V by means of links o o;

The feed mechanism M will be briefly described. In general constructionit resembles the feed-mechanism disclosed in my United States Patent No.1,058,372, dated April 8, 1913.

m (Fig. 2) is a reciprocatory slide carrying a pair of knives m madapted to separate a single can-head from the bottom of a stack ofcan-heads in the hopper m The slide on is preferably operated by a leverm connected by means of a pitman rod m to a crank pin on a gear 112?meshing with a gear m fixed upon the drive-shaft E.

m is a pusher adapted to push the separated can-heads from beneath thehopper. The feed of the can-heads is controlled by a reciprocatory rodwe having a recess m therein and connected to a bell-crank m. The pusher'm. normally rests wlthin the recess m in the rod m. hen a can passesthe bell-crank m, the bell-crank operates the rod m, lifting the pusherout of the recess m and causing it, when carried forward by the slide m,to contact with a can-head and push the same from beneath the hopper.When a can-body fails to operate upon the bell-crank m the pusher 777.will not be raised and will consequently fail to push out a can headwhen carried forward by the slide m. When 'a can-head is pushed frombeneath the hopper, it is carried forward over its can by the feed diskJ to the first seaming position, being supported by ledges h on theguide H and ledges 7' on the feed disk'J. The feed disk J is alsoprovided with ledges k for supporting the can-heads, in conjunction withthe ledges j on the lit All feed disk J1, over the cans in the firstseaming position.

The turn-table G, the feed-table H, and the feed-table I are preferablymounted upon a common or unitary frame W (Fig. 3) which slides in guides10 attached to the main frame of the machine; The frame W is adapted tobe adjusted as a whole by the hand-wheel w. justment of the machine tocans of different heights is facilitated.

The operation of the machine is as follows :Cans or bodies at m arereceived upon the turn-table G and carried to the feed-disk J. The cansare thence carried to the first seaming mechanism A past-the can-headfeed mechanism M which operates to feed a head for each can fed to the'machine. When the can reaches the first seamingposition 00 it isrounded by the feed-disks J and K and pressed upwardly by the plunger 0into engagement with the superposed can-head and against the chuck a Theshell R is thereupon lowered by the cam t, bringing the camscarried bythe slide B into contact with the shoes connected with the seaming rollsa a, forcing the seaming rolls a a into contact with the can-head toclench and partially seam the same upon,

the can. The can with the partiallv seamed head thereon then descends tothe level of the feed-table with the plunger, assisted by the knock-outU, and is thereupon fed by the disk K to a position at the front of themachine where the can can be readily and quickly observed, and removedif desired. The can thereupon passes the second seaming mechanism B. Inthis position the can is raised against the chuck'bl by the plunger]?and the seaming of the head upon the can is completed by the seamingmechanism B in a manner similar to the operation of the seamingmechanism A. The can thereupon descends with the plunger P, assisted bythe knock-outV, to the level of the feed-table, and is fed from themachine, with the assistance of an ejector X, onto the carrying-offdevice N.

The invention may receive other embodiments than that illustrated andspecifically described.
